Sounds like you don't really understand how people play this game. If X can use it, and X is the most useful, then Y and Z don't really benefit from it because it doesn't get them on an alliance. If you are going to make a job, at least figure out how it works into alliance mentality besides taking everyone's stuff. There are 16 spots and more than 16 jobs. Some jobs don't have a place already.

RDM eclipsed WHM and then SCH did the same thing. Guess what? WHM got buffed until it was the main healer again, because it's supposed to be the main healer. All you are doing with your time mage is telling RDM and SCH they should never be in an alliance because they wouldn't be needed anymore.
